CEMENT BUILDING BLOCK Filed May 4, 1936 2 Sheets-Sheet 2 Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE Claims.

This invention relates to a cement building block designed for use in any connection for which it may be found applicable, such as the walls of buildings, coolers or walk-in box constructions.

The object of the invention is to provide, in a manner as hereinafter set forth, a cement block for building insulated walls.

A further object of the invention is to provide, in a manner as hereinafter. set forth, a cement block so constructed whereby, when laid in superposed courses, it will provide the inner and outer Walls of a building and will not transfer moisture.

A further object of the invention is to provide, in a manner as hereinafter set forth, a cement block so constructed whereby, when laid in superposed courses, will provide inner and outer building walls arranged in parallel spaced relation to form an air space therebetween which may be filled with insulation material and with each block provided with means for supporting the insulation material between the walls, as well as for preventing the sagging of such material.

A further object of the invention is to provide, in a manner as hereinafter set forth, a cement building block formed of a pair of parallel spaced sections connected together by a pair of oppositely disposed bridge elements of a material which possesses non-moisture carrying and noncorrosive characteristics.

A further object of the invention is to provide, in a manner as hereinafter set forth, a cement building block formed of an outer and an inner section arranged in parallel spaced relation and connected together by a pair of oppositely inclined flanged, upstanding, corrugated bridge elements anchored at their sides within said sections and possessing non-moisture carrying and non-corrosive characteristics.

A further object of the invention is to pro- 40 vide, in a manner as hereinafter set forth, a cement building block of an inner and an outer wall forming section connected together and maintained in spaced relation by bridge elements formed in a manner to increase their torsional strength, constituting hand holds for handling the block, supports for insulation material interposed between the said sections and distributing means for such material.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a cement building block which is simple in its construction and arrangement; strong; durable; compact; conveniently handled; of a structural arrangement to form the inner and outer walls of a structure when laid in courses ;-of a form whereby the setting up of the outer and inner walls of a structure will be had at materially less expense in relation to walls constructed from wood; of a form when used to expedite Walloonstruction relative to the use of wood; so constructed as to be free of moisture conductivity; of a form for supporting insulating material therein; and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically described and are as illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a front elevation of the block and further showing in dotted lines the bridges,

Figure 2 is a top plan view,

Figure 3 is an end elevation and further showing in dotted lines the anchored sides of one of the bridge elements,

Figure 4 is a section on line 4-4, Figure 2,

Figure 5 is a section on line 5-5, Figure 1,

Figure 6 is a fragmentary view in perspective, illustrating the form of the bridge elements, and

Figure 7 is a fragmentary view in front elevation of a series of courses of the blocks to provide a wall.

The block includes front and rear sections I0, I I respectively, coupled together in parallel spaced relation by a pair of oppositely outwardly inclined sidewise flanged, spaced upstanding bridge elements I2, I3. The sections II), II preferably are constructed from cement, but it is to be understood that any other suitable material may be employed. The sections I0, I I preferably are of rectangular contour, but it is to be understood that they may be of any suitable contour desired. The sections III, II are of like contour, but the section I0 is of greater thickness than the section II. The sections I0, II have squared top,bottom, front, rear and side faces.

The bridge elements I2, I3 are of like form and each is constructed from metallic material possessing non-moisture carrying and non-corroding characteristics. The bridge elements are of a length when coupling sections I0, I I together, to have their upper and lower ends spaced respectively from the top and bottom of each of said sections. Each bridge consists of a strap-like body I4 of corrugated or step-like form formed with a set of spaced upstanding outwardly inclined stretches l constituting risers and with a set of spaced inwardly extending downwardly inclined stretches l6 constituting steps. Each of the stretches I5 is provided at its sides with outwardly directed flanges I1 disposed substantially at right angles thereto and also disposed at the same inclination as such stretch. Each of the stretches I6 is provided at its sides with depending flanges l8 disposed substantially at right angles thereto and also disposed at the same inclination as such stretch. The flanges [8 are spaced from and oppose the inner faces of the stretches l5. The elements l2, l3 have the side marginal portions embedded in the opposed faces of the sections Hi, I l and not only provide bridges between said sections, but also anchor these latter. together in spaced relation. When the elements [2, I3 are set up relative to sections Ill, II, the. exposed portions of said elements preferably will be of greater length than the embedded portions thereof.

The elements l2, 13 not only function as bridges and couplers, but further function as supports for insulation material between the block sections and distributing means for such material, as well as handholds or grips for handling the blocks. The flanges constitute anchors for the bridge elements and further increase the torsional strength of these latter.

The front. section ID of the block provides a front wall forming part. The rear section II of the block provides a rear wall forming part. When the blocks are arranged in superimposed courses, as indicated at l9 (Figure '7 they provide a front wall, a rear wall spaced from the front wall and with said walls connected together and maintained in spaced relation by the bridge elements. Preferably the blocks of a lower course will be staggered with respect to the blocks of an upper course when the walls are formed and with the blocks bound together by any suitable binding material.

What I claim is:

1. A building block comprising an inner and an outer section arranged in facewise opposed relation and spaced from each other, and a pair of bridge elements having their sides embedded in opposed faces of said sections for coupling them together and for maintaining said sections in parallel spaced relation, said elements being disposed at opposite outward inclinations from their lower ends, each of said elements being in the form of a metallic strap provided with two sets of stretches, the stretches of one set being arranged at an angle to and alternately disposed with respect to the stretches of the other set.
